There's a couple types of places where the code we write interacts with the code someone else wrote. This could be another team, a 3rd party library, or the operating system. When we interact with these components, we're tying our code to their code in some fashion. The more these…
I know I'll have disagreement on this; and I'm happy about that. One of the mechanisms I use for... what I can only call "Dependency Injection" or "Inversion of Control"... is to have multiple constructors. In the ideal I just have a single constructor. This constructor takes all the arguments.…

As I was saying; the creation is done in HackernewsNetwork#httpClient. private OkHttpClient httpClient() { return interceptorObj == null ? new OkHttpClient() : new OkHttpClient(…
The Top Stories apparently can include job postings. I have the StoryAdapter only accepting responses that have the type of "story". We need to build up a path for Jobs because it's in the payload. Well... mostly because it crashes the app when I scroll. Network We can assume that…
I'm blogging because I'm not seeing resources that covers the things I've been asked; or that I've worked out myself (like an upcoming post about maintaining Object Encapsulation). I also blog so I can google my brain later for myself or to provide my thoughts to others in a shareable…
